A YAML header:

  • Defines document-wide options
  • Specifies the output format
  • Can include several parameters

Markdown text:

  • Freely add and format text using markdown

Code chunks:

  • Evaluate code and show its output
  • Specify global and/or local chunk options (e.g. figure dimensions)
  • Also works with other languages (e.g. Python)

Rendering Quarto documents

Render from the command line:

quarto render report.qmd

Render to a specific format:

quarto render report.qmd --to html


Many IDEs like VS Code and R Studio also have buttons to render Quarto documents.

Output formats

  • Reports and general documents (HTML, PDF, Jupyter Notebook, Microsoft Word)
  • Presentations (reveal.js, PowerPoint, Beamer)
  • Interactive documents (Observable, R Shiny)
  • Books, websites and blogs
  • Journal articles
  • Your own custom formats

Presentations with Quarto


Quarto vs. R Markdown

  • Quarto is a command line tool
  • Quarto \(\thickapprox\) R Markdown 2.0
  • Quarto is language-agnostic (does not depend on R)
  • Quarto has all functionality built-in (you don’t need to install another package to create e.g. presentations)
  • The Quarto format is similar to R Markdown
  • Quarto can render R Markdown documents
  • R Markdown will continued to be supported, but Quarto is the focus of new functionality and major development
